Description

Technical Field

[0001] This utility model relates to the technical field of forward bend training equipment, specifically to a seated forward bend training device. Background Technology

[0002] Forward bend refers to a movement in which the upper body slowly bends forward, extending both hands forward to touch the feet. It improves joint flexibility, reflecting the extensibility and flexibility of the joints, muscles, and ligaments in the trunk, waist, and hips, and improving the function of the soft tissues around the joints. The seated forward bend, also known as the seated forward flexion, begins in a seated position, bending the spine above the legs and extending the arms forward towards the feet. The seated forward bend is a physical fitness test item; its purpose is to measure the range of motion of the trunk, waist, and hip joints in a static state, primarily reflecting the extensibility and elasticity of these joints, ligaments, and muscles, as well as the development level of overall flexibility.

[0031] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0032] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0033] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0034] Example 1:

[0035] A sit-and-reach training device, such as Figures 1-2 As shown, the device includes a fixing component 1 and foot pedals 2 disposed on both sides of the fixing component 1. A handgrip 3 is provided on the fixing component 1. The upper end of the fixing component 1 has multiple open-ended receiving slots 11. The handgrip 3 has a cylindrical rod-like structure, and its middle portion is embedded in one of the receiving slots 11. Inserting the handgrip 3 into different receiving slots 11 allows for multiple training positions at different distances. Specifically, the receiving slots 11 can be configured as U-shaped slots.

[0036] During training, such as Figure 3As shown, grip both ends of the hand grip 3 firmly and insert it into the receiving groove 11 to keep the hand grip 3 in a relatively fixed position, thus keeping the arm in a stable position and allowing the body to maintain a stable forward bending posture for training, improving the training effect. When it is necessary to adjust the training difficulty, the hand grip 3 can be removed from the receiving groove 11. Move the hand grip 3 upward to remove it from the receiving groove 11, and then insert it into another suitable receiving groove 11, so as to achieve training in different positions. The training difficulty can be gradually increased, thereby gradually improving the training effect. Similarly, different people can choose the matching training position according to their needs.

[0037] Specifically, the fixing component 1 is a plate-like structure, and the foot pedal 2 is a vertically arranged plate-like structure, with the foot pedal 2 fixed to both sides of the fixing component 1. The plate-like structure is simple and easy to manufacture.

[0038] Specifically, a base plate 4 is fixedly connected to the bottom of the fixing component 1, and the base plate 4 abuts against the foot pedal component 2. The base plate 4 is provided to support the overall structure, making the structure more stable; in use, the trainee's feet are placed on the base plate 4, thereby pressing the base plate 4 firmly onto the ground to prevent the trainer from moving.

[0039] Example 2:

[0040] like Figure 4-5 As shown, unlike Embodiment 1, the fixing member 1 does not need to have a receiving groove 11, and multiple hand grips 3 are provided, with multiple hand grips 3 fixed in a row on the fixing member 1. In this way, the trainee can maintain a stable posture by holding the hand grips 3 for training; when it is necessary to adjust the training position, the trainee can release the hand grips 3 and then grasp another hand grip 3 in a suitable position.

[0041] Example 3:

[0042] like Figure 6-7 As shown, unlike Embodiment 1, the upper end of the fixing member 1 has multiple open slots 12. The grip member 3 includes a grip portion 31 and a snap-fit ​​piece 32. The snap-fit ​​piece 32 is fixedly connected to the grip portion 31 and snaps into the slot 12. By cooperating with the snap-fit ​​piece, the slot 12 can be set to a width of 2-3mm, thereby reducing the size of adjacent slots 12, facilitating adjustments to smaller amounts, and allowing for gradual increases in difficulty.

[0043] Specifically, multiple snap-fit ​​pieces 32 are arranged in parallel. The spacing between adjacent snap-fit ​​slots 12 is equidistant, and the spacing between adjacent snap-fit ​​pieces 32 matches the spacing between adjacent snap-fit ​​slots 12, allowing the snap-fit ​​pieces 32 to snap into the snap-fit ​​slots 12. The parallel arrangement of multiple snap-fit ​​pieces 32 increases the contact surface between the snap-fit ​​pieces 32 and the snap-fit ​​slots 12, facilitating the snap-fit ​​pieces 32 to snap into the snap-fit ​​slots 12 and improving structural strength. Specifically, the spacing between adjacent snap-fit ​​pieces 32 can be equal to the spacing between adjacent snap-fit ​​slots 12, or the spacing between adjacent snap-fit ​​pieces 32 can be equal to the sum of the spacings between the multiple snap-fit ​​slots 12.

[0044] Example 4:

[0045] like Figure 8 As shown, unlike Embodiment 2, the fixing member 1 is a plate-like structure, and two fixing members 1 are arranged parallel to each other. The foot pedal 2 is fixed between the two fixing members, and the hand grip 3 is fixed between the two fixing members 1, and there are multiple hand grips 3. The hand grips 3 are arranged between the fixing members 1, and the arms are brought together to grip the hand grips 3 during training.

[0046] Example 5:

[0047] like Figure 9 As shown, the difference from Example 1 is:

[0048] The base plate 4 extends to the outer side of the fixing member 1 at the end away from the foot pedal 2, and a seating space is provided between the base plate 4 and the end of the fixing member 1. The base plate 4 is lengthened, and the seating space is provided on the base plate 4, allowing the trainee to sit on the base plate 4 for training. The trainee sitting on the base plate 4 compresses the trainer, preventing leg movements such as kicking when the feet are against the foot pedal 2 from pushing the trainer and causing it to shift position. Specifically, the base plate 4 can be lengthened as a whole, making it a longer base plate 4, so that the base plate 4 extends to the outer side of the fixing member 1 at the end away from the foot pedal 2; alternatively, it can be spliced ​​together, so that the base plate 4 extends to the outer side of the fixing member 1 at the end away from the foot pedal 2.

[0049] Example 6:

[0050] like Figure 10-11 As shown, unlike Embodiment 1, a slide rail 5 is fixedly connected to the fixing member 1, and a push plate 6 that slides along the slide rail is installed on the slide rail 5. The slide rail 5 is provided with a reading scale. By pushing the push plate 6 and reading the reading scale value on the slide rail 5 corresponding to the push plate 6, the range of motion of the body flexion can be measured.

[0051] The parts not covered in this technical solution can be implemented using existing technologies.

[0052] The foregoing has shown and described the basic principles, main features, and characteristics of this utility model.
